Anyone who gives you money gets a membership, it’ll be minimum of $1, but it’ll be a “pick your own price” deal.
Honestly though, you could just use a better processor that isn’t such a behemoth that they hate their customers.
That said I know several companies that for years have used Paypal's donate button to run their whole company. It's seems arbitrary.
From what I understand, they allow you to use Stripe for donations for charitable groups or projects.

Stripe is an intermediary and I would guess this has to do with anti-laundering rules. Your bank doesn't need to engage in this because they have access to everything you do with your money and has more ways to catch/stop you.
